Abstract

A graft fixation device. The device is useful for affixing a tissue graft to a bone or other body surface. The graft fixation device comprises two implantation members connected by a connecting member. The implantation members have longitudinal passageways therethrough.

Claims

1. A graft fixation device comprising:

a first implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, and a longitudinal passage therethrough;

a second implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, and a longitudinal passage therethrough;

a proximal annular face on the proximal ends of the first and second implantation members surrounding the longitudinal passage; and

,

a connecting member connecting the first and second implantation members, the connecting member having a central section, a first end extending from the first implantation member annular face at a location to one side of the longitudinal passage and a second end extending from the second implantation member annular face at a location to one side of the longitudinal passage.

2. The device of claim 1, wherein the implantation members have a series of ridges extending from the outer surfaces thereof.

3. The device of claim 1, wherein the connecting member is shaped into a configuration having a central section and rod members, wherein the rod members are substantially parallel to the longitudinal axes of the implantation members, and the central section is substantially perpendicular to the rod members.

4. The device of claim 1, wherein the connecting member has a semi-circular configuration.

5. The device of claim 1, additionally comprising a frustoconical end extending from the distal end of the first implantation member and the distal end of the second implantation member.

6. The device of claim 1, wherein the implantation members have a cylindrical configuration.
